      Chen, Dayong; Jin, Lihua; Suo, Zhigang; Hayward, Ryan C. (Royal Society of Chemistry (RSC), 2014)
      Soft, elastic materials are capable of large and reversible deformation, readily leading to various modes of instability that are often undesirable, but sometimes useful. For example, when a soft elastic material is ...
